Title: Sail reefing drum actuated by webbing
Inventor: SMITH SIMON JAMES
IPC: B63H9/10
Filed: 1986-07-07
Abstract: A sail reefing drum uses webbing instead of rope to rotate the drum. The drum comprises top and bottom flanges screwed together and locked by a screw interrupting the threads. This produces an integral sealed unit that houses bearings and a water tight seal. (figure 2 not shown). The drum rotates about a spindle fixed to the deck, is fastened to the luff or leading edge of the sail and rotates within a fixed outer casing. When tension is applied to the webbing coiled around the drum the luff or leading edge of the sail is rotated rolling the sail up thus furling or reducing the sail area. To unfurl the sail tension is put on the jib sheets unrolling the sail but rolling the webbing back on the drum. <IMAGE>

Title: Heat exchanger
Inventor: BOND ALAN
IPC: F28D7/08
Filed: 1987-08-15
Abstract: A heat exchanger (10) comprises concentric annular arrays of parallel feeder tubes (14) and receiver tubes (16) which are interconnected by generally circumferentially extending heat exchanger tubes (17). Each heat exchanger tube (17) interconnects one feeder tube (14) with a corresponding receiver tube (16) which is angularly spaced apart therefrom.

Title: Moving image projectors
Inventor: SAVAGE STEPHEN HUMPHREY
IPC: G03B21/00
Filed: 1988-02-01
Abstract: Optical images of a plurality of discrete images, of which at least some discrete images are to be projected while moving, are simultaneously projected. Each discrete image is mounted in a separate transparent carrier (16, 17, 18). Each carrier is adapted to be either stationary or to be capable of intermittent or regular motion, in a light path defined between a light source (11) and a projection lens (19) whereby images of discrete images in the light path can be projected and focused. One or more motors are provided for driving one or more of the carriers to provide the intermittent or regular motion. The thickness of each carrier and the discrete image incorporated with each carrier is kept to a minimum, at least in the direction of the light path, and the carriers and images are juxtaposed in combination in the light path so that the length of the light path occupied by the combination is less than that of the operational field of focus of the projection lens. The projected image may be that of a working clock. <IMAGE>
Patent GB-2215955-A (GB)
Title: Off screen memory
Inventor: TREVETT NEIL FRANCIS
IPC: G09G5/14
Filed: 1988-03-23
Abstract: A system includes a screen refresh (102) (i.e. on screen) and a simultaneously accessible off screen (104) memory. The system's preferred logic allows image address translation to be performed as the off screen memory is accessed, and enables high speed copy operations. Advantageously, video rate window processing is not required. The system enables video rams to be used for the screen refresh memory, whilst also allowing single ported rams to be used to hold undisplayed data. The off screen memory 104 enables fast and easy repair and movement of windows and provides the programmer with new solutions to many complex image manipulation problems. The system is designed with flexible source and destination control. Further, in one embodiment, image data can be quickly transferred in either direction between the screen refresh memory and the off screen memory with or without being manipulated by a graphics processor 100. <IMAGE>

Patent GB-2243406-A (GB)
Title: Centrifugal pump
Inventor: SMITH TREVOR STANLEY
IPC: F04D15/00
Filed: 1988-08-25
Abstract: The impeller 13 of a pump lies in a chamber 12 into which liquid can flow through an inlet 11 which can be shut by a valve 14. A plurality of chambers 25-28 are defined within a sleeve 17 by discs 21-24. Circumferential clearance between the discs 21-24 and the sleeve 17 provide flow restrictions by means of which the chambers 25-28 communicate with each other and with the chamber 12. When the valve 14 is opened the chambers 25-28 fill successively to accommodate differences between flow rates through the inlet 11 and the pump delivery, and thereby to minimise pressure surges arising from these differences. <IMAGE>

Title: Controlling die temperature in low-pressure casting process
Inventor: TANAKA KOUJI
IPC: B22D18/04
Filed: 1988-11-30
Abstract: The temperature of the casting die (12) is detected by a temperature sensor (72), and compared (78) with a preset reference die temperature range. The amount of cooling water to be supplied to the casting die is controlled (78; 84, 88; 86, 90) based on the result of the comparison. When the detected temperature of the casting die falls in the preset reference die temperature range, filling of the die cavity with molten metal starts. When the cavity is full, the contents are pressurized during solidification. The pressure and initial stage cooling selection are chosen by comparison of die and molten metal temperatures (from sensors (72, 73) with preset reference temperatures. The speed of die filling may have been similarly determined. Extended cooling under pressure is also selected with reference to a preset reference temperature for die opening. Forced water-cooling can be selected from a range of preset patterns according to whichever temperature range, above a given desired temperature, the actual temperature(s) fall in. <IMAGE>
